Los intereses estratégicos de EEUU, Rusia, China y Japón como determinantes de la estrategia de mantenimiento de la Estructura en la Península Coreana. 2003-2013.

El propósito principal de esta monografía es ofrecer una perspectiva crítica sobre el conflicto latente en la Península Coreana, haciendo un acercamiento al mismo desde un marco teórico asentado en el realismo estructural de Kenneth Waltz. De este modo, se busca responder a cuestiones sobre los intereses estatales como fundamento básico de las estrategias de mantenimiento de la Estructura en regiones geopolíticamente sensibles. Al final, se llega a la conclusión afirmando que la Estructura ejerce una serie de funciones para garantizar su preservación mediante una acción de convergencia en la conducta de los Estados. Esta realidad ha mantenido a la Península Coreana sin un conflicto bélico en los últimos 50 años, muy a pesar de estar al borde del mismo en varias ocasiones, ya que de llegarse a presentar se rompería la estabilidad de la región, y por ende el Equilibrio de Poderes estaría en grave riesgo.

Don't make war, make elections : Franchise extension and violence in XIXth-century Colombia

This paper studies the effect of strengthening democracy, as captured by an increase in voting rights, on the incidence of violent civil conflict in nineteenth-century Colombia. Empirically studying the relationship between democracy and conflict is challenging, not only because of conceptual problems in defining and measuring democracy, but also because political institutions and violence are jointly determined. We take advantage of an experiment of history to examine the impact of one simple, measurable dimension of democracy (the size of the franchise) on con- flict, while at the same time attempting to overcome the identification problem. In 1853, Colombia established universal male suffrage. Using a simple difference-indifferences specification at the municipal level, we find that municipalities where more voters were enfranchised relative to their population experienced fewer violent political battles while the reform was in effect. The results are robust to including a number of additional controls. Moreover, we investigate the potential mechanisms driving the results. In particular, we look at which components of the proportion of new voters in 1853 explain the results, and we examine if results are stronger in places with more political competition and state capacity. We interpret our findings as suggesting that violence in nineteenth-century Colombia was a technology for political elites to compete for the rents from power, and that democracy constituted an alternative way to compete which substituted violence.

Why peace processes fail or move forward? Negotiations in Colombia with FARC and AUC (1998-2003)

Este trabajo examina la teoría sobre guerras civiles y resolución de conflictos con el fin de contestar la pregunta: ¿por qué fracasan o progresan los procesos de paz? Se miraron los procesos de paz en Colombia en los últimos cinco años cuando comenzó y fracasó el proceso de paz con las Fuerzas Armadas Revolucionarias de Colombia, FARC y comenzaron con las Autodefensas Unidas de Colombia, AUC. La teoría revela la relevancia de factores económicos, políticos, participación externa y militares para explicar por que fallan o prosperan los procesos de paz. Por su parte, el fracaso de las negociaciones con las FARC puede explicarse por razones de estrategia militar, el rol de la violencia durante la negociación y la falta de participación internacional. De otro lado, evitando todos los puntos sensibles de la negociación inicial, las AUC ganaron apoyo de la opinión publica y la confianza del gobierno para iniciar los diálogos. De esta forma, tenemos dos procesos recientes en Colombia para analizar: uno que fallo y el otro que esta progresando. El análisis de estos procesos puede ayudarnos a contestar la pregunta inicial de este trabajo.

Natural resource windfalls and efficiency of local government expenditures: evidence from Peru

We study the role of natural resource windfalls in explaining the efficiency of public expenditures. Using a rich dataset of expenditures and public good provision for 1,836 municipalities in Peru for period 2001-2010, we estimate a non-monotonic relationship between the efficiency of public good provision and the level of natural resource transfers. Local governments that were extremely favored by the boom of mineral prices were more efficient in using fiscal windfalls whereas those benefited with modest transfers were more inefficient. These results can be explained by the increase in political competition associated with the boom. However, the fact that increases in efficiency were related to reductions in public good provision casts doubts about the beneficial effects of political competition in promoting efficiency.

Natural resources, redistribution and Human capital formation

How do resource booms affect human capital accumulation? We exploit time and spatial variation generated by the commodity boom across local governments in Peru to measure the effect of natural resources on human capital formation. We explore the effect of both mining production and tax revenues on test scores, finding a substantial and statistically significant effect for the latter. Transfers to local governments from mining tax revenues are linked to an increase in math test scores of around 0.23 standard deviations. We find that the hiring of permanent teachers as well as the increases in parental employment and improvements in health outcomes of adults and children are plausible mechanisms for such large effect on learning. These findings suggest that redistributive policies could facilitate the accumulation of human capital in resource abundant developing countries as a way to avoid the natural resources curse.

Danish razors and Swedish rocks: Cosmology and the Bronze Age landscape

A recent study has suggested that the decorated Bronze Age metalwork of South Scandinavia depicted the path of the sun through the sky during the day and through the sea at night. At different stages in its journey it was accompanied by a horse or a ship. Similar images are found in prehistoric rock art, and this paper argues that, whilst there are important differences between the images in these two media, they also signal some of the same ideas.

Sailing through stone. Carved ships and the rockface at Revheim, southwest Norway

The relationship between rock art and the material qualities of the rock surface on which it is executed is investigated. The case study of Revheim, Rogaland, Southwest Norway, is the starting-point for a discussion on the way in which the contours of the rock, quartz outcrops and the flow of water across the rock surface affect the placement of images on the rock. It is argued that a fuller examination of the interrelationship between rock and rock art provides a more coherent interpretation of rock art images.

Past, present and future mathematical models for buildings (ii)

This article is the second part of a review of the historical evolution of mathematical models applied in the development of building technology. The first part described the current state of the art and contrasted various models with regard to the applications to conventional buildings and intelligent buildings. It concluded that mathematical techniques adopted in neural networks, expert systems, fuzzy logic and genetic models, that can be used to address model uncertainty, are well suited for modelling intelligent buildings. Despite the progress, the possible future development of intelligent buildings based on the current trends implies some potential limitations of these models. This paper attempts to uncover the fundamental limitations inherent in these models and provides some insights into future modelling directions, with special focus on the techniques of semiotics and chaos. Finally, by demonstrating an example of an intelligent building system with the mathematical models that have been developed for such a system, this review addresses the influences of mathematical models as a potential aid in developing intelligent buildings and perhaps even more advanced buildings for the future.
